英文摘要	Microplastic pollution is now pervasive in a wide range of environments as a potential threat to organisms and ecosystems. Qinghai-Tibet Plateau, as the third pole of the world and the water tower of Asia, there are few studies on microplastic pollution. This review summarizes the abundance, characteristics, sources, and transport of microplastics in surface water, sediment, soil, atmosphere, and glacier of the Qinghai-Tibet Plateau. The abundance of microplastics in surface water of the Qinghai-Tibet Plateau ranged from 0 to 3050 items/m(3), 10-2643.65 items/kg in sediment, 0-3660 items/kg in soil, and 0-36.09 items/L in glacier. Microplastics in surface water, sediment, atmosphere, and glacier of the Qinghai-Tibet Plateau are dominated by fibers, with proportions of 48%, 47%, 92%, and 50% in that order. The sources of microplastic pollution in the Qinghai-Tibet Plateau are mainly from local human activities, and atmospheric transport is a substantial source. The preliminary pollution load index (PLI) assessment indicates that ecological risks from microplastic concentration loads are at low levels in all environments of the Qinghai-Tibet Plateau. The polymer risk index (H) indicates that ecological risks from polymer toxicity of microplastics are at high levels in all environments of the Qinghai-Tibet Plateau. Finally, we suggest future research directions and management measures for local microplastic pollution, which are necessary to alleviate the pollution problems in high altitude remote mountainous ecosystems.
